Spi 29-586-5 Class Zz Plus Plug Gage 0.586 in

Product Description

The SPI 29-586-5 is a Class ZZ Plus plug gage designed for go/no-go inspection of drilled, reamed, or machined holes. It checks that a bore or hole has been produced to the correct size within a defined tolerance range. The gage measures a nominal diameter of 0.586 inches with a tolerance of 0.0002 inches, making it appropriate for standard-precision inspection tasks in production or maintenance environments. Constructed from steel, it provides the durability needed for repeated use on the shop floor. Machinists, toolmakers, and quality-control technicians are the typical users of this type of gage.

This plug gage is suited for use in manufacturing, machining, and mechanical maintenance settings where hole size verification is required. It fits into standard inspection workflows for residential and commercial mechanical equipment manufacturing, general metalworking, and precision assembly operations. The 0.586-inch diameter makes it a working gage for checking bores of that nominal size in steel, aluminum, cast iron, and similar workpiece materials.

Compatibility

Designed as a standard Class ZZ Plus plug gage for go/no-go inspection of holes with a nominal diameter of 0.586 inches in general machining and inspection applications.

Installation Notes

Plug gages are handled and used by machinists and quality-control technicians, not installed in a system. Clean the gage and the bore being checked before use to prevent measurement error from debris or burrs. Store the gage in its case when not in use to protect the precision-ground surface from nicks and corrosion. Do not force the gage into an undersized hole, as this can damage the gage surface and compromise measurement accuracy.
